The classic side of the product covers the essentials most people need every day: viewing and editing PDF text and images, converting between PDF and Office/image formats, OCR for scanned files, merging, splitting, compressing, watermarking, signing and annotating. Because everything runs in the browser with companion apps for Windows, Mac, iOS and Android, the same account and files travel with you across devices. The AI layer is where the product has expanded most. An AI agent lets you chat with an uploaded document, ask follow-up questions and trace answers back to citations, while a separate chat experience works on YouTube videos. Document translation preserves the original layout across 20+ languages, including scanned and image-based PDFs, and structured data extraction turns invoices, receipts, bank statements and purchase orders into editable spreadsheets. Rounding out the suite are an AI PPT generator, mind-map and summary generation, watermark and sticker removal, text and logo erasing, document enhancement for scanned pages and an AI invoice generator. Pricing follows a freemium model with a free tier (10MB file limit, watermark on some exports) and paid plans that add unlimited file sizes, batch processing, cloud storage and monthly AI credits. Individual subscriptions start around $5.99 per month, with a yearly option near $15.99 and a one-time lifetime plan; credits are consumed per AI action, so heavy AI users can top them up. Team, business and education plans are available on request. **Pricing & Plans:** Freemium. A free plan covers basic PDF tools with a 10MB file cap; paid plans start around $5.99/month, with a yearly tier and a one-time lifetime option. AI features consume monthly credits that differ by plan. - **AI document agent and chat:** Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from.

It focuses on the problem that highlights are easy to save and hard to find again: you remember an idea but not the book it came from. By collecting Kindle and KOReader highlights into one library, it lets you search a few words and jump back to the passage, with notes kept alongside it in your existing note-taking app. The project deliberately offers multiple editions so you can match it to where you read and where your notes live. Unearthed Local is a one-time-purchase desktop app for Windows, macOS and Linux that stores your library on your own computer, exports Markdown to an Obsidian vault and connects to Craft, and also saves articles and RSS feeds. Unearthed Online is a $5/month browser edition that is open source under GPL-3.0 and connects to Obsidian and Notion while sending daily reflections to Supernotes. Unearthed Mobile is a paid phone app for reading articles and capturing passages on the go. Beyond books, Unearthed supports your own sources so that quotes, ideas and facts that did not come from a book still live in the same system, and daily reflections bring saved passages back for another look. It is positioned as a Readwise alternative with a strong open source and self-hosting story, though AI summaries and book chat are limited to the Online subscription and the Capacities integration is still pending. **Pricing & Plans:** Free/open source core with paid editions. Unearthed Online costs $5 per month. Unearthed Local for Windows, macOS and Linux is a one-time purchase, and Unearthed Mobile is a separate one-time purchase app, with no Obsidian plugin required for Local exports. - **Kindle and KOReader sync:** Import Kindle and KOReader highlights into a single searchable library, so you can find a passage without reopening every book. - **Notes app integrations:** Send books, highlights and daily reflections to Obsidian, Craft, Notion and Supernotes, with Capacities support in the works. - **Custom sources for your own ideas:** Create your own sources for quotes, ideas and facts so short-form inspiration sits beside your book highlights. - **Articles and RSS feeds:** Save web articles and follow RSS feeds in Unearthed Local and Mobile so new posts appear next to your reading highlights. - **Open source and self-hostable:** Unearthed Online is GPL-3.0 open source, with the browser extension, Obsidian plugin and KOReader plugin published on GitHub. **Strengths:** Consolidates Kindle and KOReader highlights into one searchable library; Connects to Obsidian, Craft, Notion and Supernotes; Open source (GPL-3.0) with self-hosting options; Local edition keeps your library on your own computer **Limitations:** AI summaries and book chat are only on the Online subscription, and Capacities support is not yet available; Local and Mobile editions are separate paid apps, not one purchase for everything; Core focus is Kindle and KOReader, so other e-readers get less coverage; Online edition depends on a monthly subscription for continued web access [Profile (Markdown)](https://openaitools.app/tool/unearthed.md) ## Frequently Asked Questions ### How do LightPDF and Unearthed compare in monthly traffic?
